HINGE.

SPECIFICATION forming part of Letters Patent N 0. 552,404, dated December 31, 1895.

Application filed May 20, 1895. Serial No. 549,955. (No model.)

T0 at whom it may concern:

Be it known that I, EDWIN F. TILLEY, of New York, in the county and State of New York, have invented a new and Improved Hinge, of which the following is a full, clear, and exact description.

The invention relates to an improvement in that class of hinges wherein the sections are not permanently connected by means of the usual pintle, but which are so constructed that they may be securely mounted on each other and yet be capable of easy separation, such hinges being especially adapted to uses which require the frequent removal of the hinged partas, for example, in folding couches and beds, tool-chests, and similar devices. r

The object of this invention is to construct the parts so that the hinge will be more simple and durable than heretofore and also to make the device so that the swing of the sections will be limited.

To this end the invention consists in certain novel features of construction and combinations of parts, which will be fully described hereinafter and finally embodied in the clainis.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 represents a perspective View of my improved hinge, showing the sections thereof connected and showing them moved to the limit of their outer stroke. Fig. 2 is a cross-section of the hinge, the parts being in the position shown in Fig. 1. Fig. 3 is also a cross-section showing the parts closed or moved in close engagement. Fig. 4 is a detail perspective View of one section of the hinge; and Fig. 5 is a similar view of the remaining section, the said sections being shown as standing alone in each view.

The reference-letters A and B indicate respectively the two sections or parts of the hinge, each of which may be constructed of any suitable material, brass or malleable iron being preferable. The two sections are of equal length, while the section A is slightly 'wider than its companion; and each section is formed with screw-openings 10, through which securing-screws may be passed to hold the parts in place.

The section A is formed with the tongue 11 integral therewith, and the said tongue is of a length equal to about one-half the length of the section and located midway the same, being shaped with a curved outer face 12 and plane face 13. This plane face 13 is disposed at an obtuse angle from the plane of the section A, while the curved face 12 bends around into the plane of the face 13 so as to meet the same.

The section B has formed integral with its inner edge and near the ends thereof the cylindrical portions 14, which have the appearance of the usual pintle-sockets and which have connected thereto the vertical strip 15. This strip 15 extends from one of the portions 14 to the other and is formed with a slightlycurved inner face 16, terminating in a plane face 17, which extends therefrom at a tangent and which is disposed at right angles to the disposition of the plate B, to which it is attached. The plate B, at a point in its lateral extent which is vertically aligned with the inner sides of the cylindrical portions 14, bends inwardly to form a slightly-beveled face 18, and this face 18 is of a width equal to onerhalf that of the plane face 13 on the tongue 11.

Contiguous to the outer edge of the beveled face 18 is the secondbeveled face 19,which is also formed on the section B and which is slightly less than at right angles to the face 18 and of a width a little more than one-half that of the plane face 13 on the tongue 11.

By reference to the drawings it will be seen that owing to the peculiar construction just explained the sections A and B of the hinge will be capable of lying snugly against each other in the closed position, and when this position is assumed the beveled face 18 will lie snugly against the inner half of the plane face 13 of the tongue 11, while the remainder of said plane face will project across in a slightly-diagonal direction to the curved portion 16 of the strip 15.

In the open position (see Fig. 2) the faces 18 and 19 willbe disengaged and the formerlydisengaged portion of the face 13 will lie snugly against the beveled face 19, while the plane portion 17 of the strip 15 will engage with the inner part of the tongue 11, and by means of these two engagementsnamely, between the faces 13 and 19 and the tongue 11 and face 17-the further outward movement of the section A is effectively prevented and the two sections held incapable of movement beyond that which will place them at right angles to each other.

It will be seen that when the sections are in the position of Fig. 2, which is their open position, the section A may not be disconnected from the section B, nor vice versa, because the beveled face 13 will engage with the face 19 and firmly bind the parts against each other; but this disconnection may be effected when the parts are in any position other than this as, for example, in the position of Fig. 3. In use,it will never be desirable to disconnect the sections when the section A has been opened to the position shown in Fig. 2, for the salient feature of my invention lies in that construc tion which makes this disconnection impossible. \Vhen the sections are closed they may be readily disconnected, and it is the purpose of the invention that they shall be.

It is not necessary for me to explain in detail the arrangement of the hinge in connection with the devices for which it is used, since this is the same as in all similar appliances. It will sufiice therefore for me to say that the section B is to be secured to the horizontal and stationary part of the device and the section A to the swinging portion. hen the parts are so arranged the cylindrical portions 1% serve to receive the weight of the section A and the part of the device which is hinged thereto and which swings with it. It will be understood, therefore, that the portions 14 perform the same function that is performed by the usual pintle in the hinges which have their sections locked together.

It will be observed that the essential feat'ure of my invention lies in that construction which prevents the sections from disconnection at the open position, for in use on a couch the top must be secure on the body at this position, and by means of my invention this secureness is insured.

Fig. 2 plainly shows how' the faces 19 and 13 bind against each other and make disconnection impossible at the open position.

The specific description of parts 1% and 15 is that hereinbefore used with reference to them; but it will be seen that they form substantially an opening having closed sides, and this is a more general specification.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. A hinge, consisting of two separable sections, one of which is provided with a tongue projecting from the middle of one edge and having a slightly diagonal plane face and a curved face opposite to the plane face and extending around to the same, the other section being provided with two cylindrical portions arranged one at each end of one edge and connected by a strip running parallel with the section and having on the side which is adjacent to the section a curved face contiguous to a plane tangential face, the said latter section also having at one side of the edge to which the cylindrical portions are attached, a slightly beveled face and having at the opposite side of the same edge a second beveled face, the said second beveled face being extended a little less than at right angles to the first beveled face, substantially as described.

2. A hinge, consisting of two sections, one of which is formed with an opening extending through it and having closed sides, one side of said opening being beveled and the remaining section having a tongue which fits within the opening and which has the side adjacent to the beveled side of the opening also beveled, so as to conform to the bevel of said opening-side, substantially as described.

7 3. A hinge having two sections, one of which is formed with an opening therein, one side of said opening being beveled and the opposite side of said opening being curved and having a plane face extending tangentially to the are of said curve, the remaining section having a tongue with the side ad jacent to the beveled side of the opening correspondingly beveled and with the side adj acent to the curved side of the opening curved to conform to said curved side, substantially as described.

4. A hinge consisting of two sections, one of which is formed with two cylindrical projections at one edge and with an opening between said projections, one side of the opening being form ed with a beveled face and the remaining section having a tongue which fits within the opening and which has a bevel on the side adjacent to the beveled side of the opening, portions of the edges on the second section being in slidable connection with the respective cylindrical projections of the first section, substantially as described.
